This application is in part a division of our application filed April 26, 1930, Serial No.

447,5 34 (Case 7727) for attachment for post- 'nection with various kinds of machines where- Y in such a strip or web is to be severed.

In the accompanying drawings we have illustrated two practical embodiments of the invention and will explain the same withv reference thereto asillustrative thereof; but we do not consider the invention limitedr in scope to the specific constructions shown. In the claims the essential featuresof the invention and the novel features. of construction and novel combinations of parts for which protection is desired are set forth. f

In said drawings:

Fig. 1 is' a front view of the cutter.y Fig. 2 is a plan view. Fig. 3 is a rear view and Fig.

4 an end viewof such cutter. Fig. 5 is a transverSe section showing the cutter open for the passage of a strip or web. Fig. 6 isa similar view showing the position of the parts upon severing the web or strip. Fig. 7 is a front view of Ya modification of the cutter. Fig. 8 isa longitudinal horizontal section on'line 8-8, Fig. 7. Fig. v9 is a transverse section of 1' such Vcutter showing the parts inp'ositio'n for passage of a web before severing. Fig. 10 is a similar view 4showingvthe position of the parts just after severing the web. Fig. 11 is a side view of the cutter detached. f

As shown in Figs. 1 to 6the cutter comprises a body 10 which is longitudinally bored and screw threaded as indicated, butthe rear part of the body is recessed longitudinally as at 10a the recess extending into the threaded portion, as shown in Figs. 2, 5. l

Entered in body 10 and engaging the threaded portion thereof is a cutter formed 'of a threaded cutter rod 11 which has part of its threaded portion corresponding Vto the recess 10a out away as at 11a. Thebody 10 has a slot 10b opposite the cut awayportion through which slot passes the webor strip W which is to be severed. .The slot 10b is pref-y tending the whole length ofthe out away por-4 10c and sever the stripn W.

' erably longitudinally inclined at an obtuse an@` gle to the rod (Figs'l and3) to give a shear Y, f

to the cutting edge.` The cut away portion 1101i of the rod (Figs. 1 and 11)" leaves a fiatv extionlOa of the body so that the strip or web W may be readilythreaded between these cut indicated in Figs. 1 to 5.

The cutter rodmay be rocked or turned by 4any suitable means and wheni said rod is away portions when rod llis in the position rocked its finely serrated edge 110 (produced bythe cut threads of the rod, Fig. 2) will pinch thejpaper againstthe serrated edge'lOc of the body (produced by thecut threads atf the upper sidey of the slot 10b, Fig. 1) and these line serrations will cleanly sever the web or strip and the slight relative longitudinal movement of the rod and body due to the threads facilitates the severance of the web or stripl ofy material inserted therebetween.

Thev rod may be operated manually or mechanically by any suitable meansgand, when applied to an attachment such as shown'in our aforesaid application Serial No. 447,534 by; the means indicated in Figs. 4-6. In such case `a member having two arms 12 and 12a isl Y attachedfto the projecting end of rod 11.

i Such membercan be fitted on the square end of the cutter rod and secured by a screw 12s and' its armsf12 and 12`aare adapted to be engaged by areciprocating bar 8; said bar havinga slot 8g in its end which as the bar moves to the right first engages the arm 12a and :rocks the member and cutter rod 11 clock' wise; suchmovement engaging arm 12 with the4 slot 8ginthe bar 8. This rocking'movement of the cutter rod 11a causes its serrated kedge 110 to cooperate with the serrated edge in Figs. 1-6. The threaded rod 11s is fiizedly mounted, and as shown is secured in lugs 13a on a bracket 13 which may be fastened to a suitable base or to the machine with which the cutter is to be used. The sleeve nut 108 is rotatably ymounted upon the screw 11s, and the arm 12a may be attached to this'casing, and operated as above described whereby at each reciprocation of the bar 8 the sleevexnut '10s is rocked to sever the web W as indicatedy 'in Figs. 9 and 1 0. y Obviously the invention is "not ydependent upon the partic-ular means forMoscillating the cutter rod 11 or the casing member`10s as theyV can be operated by. various means, asv

will be obvious to a mechanic, either manually or by proper connections with the operative l-mechanism of the machine on which the cutter is used. The particular means for rocking the movable member ofthe cutter not being an essential feature of the present invention. i

vIn a cutter having members with intermeshing serrated edges, similar to the screw and nut type here illustrated, even if the cutting edges become dull, the paper stripicannot be drawn inbetween them as in the case of dull,.or poorly set shears or scissors; as the lpaper has not suiiicient tensile strength to stand the distortion necessary tol allow it to follow the sinuous line of cleavage between 'the serrated edges of the rod and body; and

therefore the strip will be cleanly severed when the members are sharp, or cleanly torn apart when they are dull.

' We claim:

1. A paper cutting device consisting of a threaded member having a longitudinal recess in its threaded portion the cut threads providing a serrated edge on said recess adapted to sever the paper. f

Y 2. A paper cutting device consisting of a body having a slot with a serrated .edge at one side, and a rod extending longitudinally of the slot also having a serrated edge, the paper being free to pass between the serrated edges of the body and rod in the normal posi- AVtion of the rod, and means for relatively rotating` the body and rod to sever the paper. ,3.

A paper cutting device consisting of a body having a slot with a serrated edge, Vand a threaded rod extending longitudinally of the slot having a recess coincident with the slot the cut threads imparting a serrated edge to the recess,said parts in normal position permitting free passage of the paper through the slot, and means for relatively rocking the bodyV and rod tosever'the paperp'by theaction j of the serrated edges. y

6.V A' paper cutting deviceA consistiirgivof a body having a slot with a serrated vedge at one side, a threaded rod -extending longitudinally of Y the slot, and having a recess coincident with the Vslot, and cut threads of therod providing a serratededge adapted to cooperate with the serrated edge of the slot; the web or strip being free vto pass between the vserrated edges of the bodyand rod in one position thereof; and means for relatively ,-1,
